The Final Work of a Mystery Novelist

She chose to endure it - for the sake of her daughter, she would not expose it. But he secretly collected evidence and profiled her husband's every move like a profiler. He is highly intelligent, logical and confident that everything is under control. She counterattacked in his own way: instead of killing the body, destroy the soul first. When the "accident" was about to happen, she used the cruelest reversal to make him fall from "master" to "hypocrite murderer". The most perfect mystery is never written by the murderer.
